Detecto vs Originality.ai

Detecto is a web service that estimates AI-generation likelihood for text, images, video, and audio, returning calibrated probabilities, supporting evidence, and reviewer reports. Text reports can highlight sentences and show perplexity, burstiness, and a confidence band. Image reports include generation likelihood, a region heatmap, surface-artifact flags, and metadata-integrity checks. Reviewers can add notes, save reports, export PDFs, and share controlled links. Scans and reports are private to the account by default; ephemeral mode allows scanning without storing content or reports. Detecto says submissions are never used to train its detection models. The service is aimed at editors, educators, newsroom verification desks, PR teams, agencies, publishers, and universities. A free tier includes starter credits and full report fidelity without a card. Student costs $6.99 a month billed $83.88/yr; Pro costs $19.99 a month billed $239.88/yr; Max costs $59.90 a month billed $718.80/yr. Scores are probabilistic, not proof, and short or translated text can affect detection.

Originality.ai provides tools for checking AI-generated text, plagiarism, facts, readability, grammar, spelling and content quality. Its free Basic plan costs $0.00 per free and provides three AI scans per day, with up to 2,000 words per scan. The AI detector offers configurable allowances of 0%, 5%, 15%, 25% or 40%. A website scanner can crawl a site, identify pages likely to contain AI-generated content and run scheduled scans. The browser extension scans Google Docs, web pages or selected text, and includes writing replay, typing behavior insights and shareable reports. A REST-based API submits text for AI and plagiarism scans and returns detailed results; the maker says AI detection supports 30 languages. API AI scans require at least 50 words, and the help page says accuracy decreases below 100 words. Originality.ai describes detection results as probabilistic estimates that may produce false positives or false negatives, not conclusive proof. Pro costs $12.95 per month billed yearly, with a monthly option at $14.95 per month. The service is available through web, API and extension.
